Struct wr_glyph_rasterizer::FontInstance

pub struct FontInstance {
    pub base: Arc<BaseFontInstance>,
    pub transform: FontTransform,
    pub render_mode: FontRenderMode,
    pub flags: FontInstanceFlags,
    pub color: ColorU,
    pub size: FontSize,
}

A mutable font instance description.

Performance is sensitive to the size of this structure, so it should only contain the fields that we need to modify from the original base font instance.

Fields

base: Arc<BaseFontInstance>

transform: FontTransform

render_mode: FontRenderMode

flags: FontInstanceFlags

color: ColorU

size: FontSize

Trait Implementations

impl Clone for FontInstance

fn clone(&self) -> FontInstance

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FontInstance

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for FontInstance

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl MallocSizeOf for FontInstance

fn size_of(&self, _ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl Ord for FontInstance

fn cmp(&self, other: &FontInstance) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for FontInstance

fn eq(&self, other: &FontInstance) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for FontInstance

fn partial_cmp(&self, other: &FontInstance) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for FontInstance

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Deref for FontInstance

type Target = BaseFontInstance

The resulting type after dereferencing.

fn deref(&self) -> &BaseFontInstance

Dereferences the value.
